C132 BEARING FCT. CLES.

I hereby declare the following to'bc a full,

clear, and exact description or' the invention, such as will enableothers skilled in the art to which it appertains io make and use thesame. y

Our invention relates to improvements in side bearings for cars and thelike, of the type disclosed and broadly claimed in a copendingapplication executed of even date herewith and iled by Franklin L.Barber and Edwin W. Webb and also an application executed by Edwin lV.Webb of even date herewith. l

To the above end, generally stated, the invention consists of the noveldevices and combinations of devices hereinafter described and defined inthe claims.

In the accompanying drawings which illustrate the invention, likecharacters indicate like parts throughout the several views.

Referring to the drawingsz.

Figure 1 is a plan View of the improved side bearing;

Fig. 2 is a view partly inside elevation and partly in longitudinalvertical section taken on the line 2-2 of Fig. 1;

Fig. 3 is a horizontal section taken on the line 3-3 of Fig. 2;

Fig. 4 is a transverse vertical section taken on the line 1 -4 of Fig.2;

Fig. 5 is a detailed view principally in section taken on the line 5 5of Fig. 2; and

Fig. 6 is a View corresponding to Fig. 2 but illustrates the movableparts of the side bearing moved to one of their extreme positions.

The numerals 7 and 8 indicate, respectively, the body bolster and thetruck bolster of a railway car.

The improved side bearing is carried by a body bolster 7, and includes acast rectangular housing 9, with an open top and bottom. Cast with theupper portion of the housing 9, at the corners thereof, are fourhorizontally disposed ears 10, having bores l1, through which rivets orother fastening means, not shown, are passed to rigidly secure the sidebearings to the body bolster 7.

Epzcmicn cf Letters Patent.

Patented Nov. 12, 1918.

The top surfaces Cf the housing 9 and ears l0, extend in an obliqueplane to conform to the surfaces ofthe body bolster to which they aresecured and have flat engagement therewith.

On the inner surfaces of the end walls of the housing 9 lare shoulders12 on which is loosely supported a cover 13, which lits within thchousing 9 and is held thereby, against horizontal movement. The uppersurfaces of thc cover 13 extend in the saine oblique plane as thc uppersurfaces of the housing 9 and cars 10, so as to bear directly againstthc body bolster 7. T he top of the cover 13 is cored for the sake oflightness and the saving of material. The ends of the cover 13 terminateshort of the respective ends of the housing 9 and cast therewith, at thebottom thereof, are small anges 14:, provided for a purpose that willpresently appear. On the bottom of the cover 13, at the ends thereof,are guides 15 which slidably receive and support a wearing plate 16.When the cover 13 is in position in the housing 9 the wearing plate 16is held thereby, against removal from the guides' 15.

In each end of the housing 9, is formed a pocket 17 and extending intothe housing, at the bottom of each pocket, is a bifurcated bracket 18.On the bottom of the pockets 17 and on the upper faces of the brackets18 are formed roller seats 19 that have diverging contours which extendfrom the centers thereof.

A pair of rollers 20 are mounted in the seats 19 and support the ends ofa self-centering carrier 21 in the form of a single bar. The ends of thecarrier 21 work in the pockets 17 and have on their lower edges, rollerseats 22 of the same shape as the roller seats 19 with the exceptionthat they are inverted with respect thereto. A pair of longitudinallyspaced fulcrum notches 23 are formed in the upper edge of the carrier21. Hub-like stops or extensions 24 are formed on the vertical faces ofthe carrier 21 centrally between the notches 23.

The body bolster 7 is supported from the truck bolster 8 by a pair `ofrockers 25, located, the one in advance of the other. These rockers 25are provided with apertures 26 which extend in the direction of therocking movement thereof and through which aperture the carrier 2lextends. Fulcrum pins 27 carried by the rockers 25, in the aperbe movedtherewith.

tures 26, extend through the fulcrum notches 23 and are normally out ofengagement t-herewith. The upperl segmental bearing surface of therocker 25 supports the wearing plate 16 and the lower segmental bearingsurfaces thereof, rest on a bearing plate 28 secured to thetruclrbolster 8.-

Normally the rockers 25 rest on the wearing plate 28 and support the carbody and load through the wearing plate 16 and cover 13. I/Vhen the loadis thus supported the fulcrum pins 27 are entirely out of contact withthe fulcrum notches 23 and as long as the load continues on the rockersthe movement is simple and said rockers will move back and forth on thewearing plates vand carry with them the carrier 21. V

I/Vhen the car is on a -curve the rockers 25 will be positioned, asshown in Fig. 5, to a greater 0r less degree and as the rockers 25 areinterlocked to the carrier 21 by the notches 23 and pins 27, saidcarrier will This movement of the carrier 21 moves certain of theinclined surfaces of its roller seats 22 onto the rollers 20 and alsomoves said rollers onto certain of the inclined surfaces of the rollerseats' 19. With the rollers 2O thus positioned in the roller seats 19and 22, the carrier 21 is lifted into a position to bring the fulcrumnotches 23 in said carrier into close relation to the fulcrum pins 27.

If the rockers 25 continue to support the load from the wearing plate 28until the car passes beyond the curve the movable parts of the sidebearing will return to normal positions under the action of the holsterswith respect to each other, but if the car body lifts with respect tothe car truck, the carrier 19 will lift the rockers 25 out of engagementwith the wearing plate 28 and said rockers will then swing on thefulcrum pins 27, in the fulcrum notches 23, into perpendicular or normalpositions. This swinging movement of the rockers 25 will carry with themthe carrier 21, which carrier will at the same time assist inpositioning the rockers. The rollers 2O and carrier 21 will at the sametime self-center themselves and also assist in positioning the carrier19. It will thus be seen that the rockers 22 will instantly return tonor,- mal positions and will again be ready to support the load when thecar body again assumes a normal position. Extreme movements of therockers 25 are limited by engagement thereof with the hubs 24 andflanges 29 on the lower inner edges of the ends of the housing 9, (seeFig. 5).

In assembling the improved side bearing the rollers 20 are iirst mountedon the seat 17 and the end portions of the carrier 21 inserted throughthe apertures in said rockers and the pins 27 interlocked with thenotches 23. The assembled rockers and carrier are then placed in thehousing with the ends of said carrier resting on the rollers 20. Thewearing plate 16 is then secured to the cover 13 and said `cover placedvin the housing and supported on the shoulders 12. To hold the parts inassembled relation before the side bearing :is secured to the bodybolster, the upper edges of the end walls of the housing 9 are bentinward as indicated by broken lines at 30 by poundingor -otherwise sothat they will overlie the flanges 1&1 on the ends of the cover 13 andthereby hold said cover in position.
